24-Methyl-25-ethyldammarane derivatives from Pilocarpus spicatus

Phytochemistry 35(3): 739-743

24-Methyl-25-ethyldammarane derivatives from Pilocarpus spicatus

From the ethanol extracts from leaves of Pilocarpus spicatus 3 beta-acetoxy-24-methyl-25-ethyl-20,24-epoxydammarane and 3-oxo-24-methyl-25-ethyl-20,24-epoxydammarane were isolated. Structure determination of these natural products was accomplished by spectrometric analysis, chemical transformation and X-ray crystallographic studies.
